- Buttermilk: Adds tenderness and a subtle tang that balances the lemon
- Vanilla extract: A splash deepens the overall flavor without overpowering

Pro Tips
I often find that pausing at each stage lets the flavors settle like a soft sigh. The lemon zest, once folded in, continues to release its fragrant oils while the cake bakes, turning the kitchen into a quiet garden. So, take a breath, enjoy the moment, and let the simple act of whisking become a gentle meditation.

Ingredients
Cake Batter
- 01 2 cups all‑purpose flour
- 02 1 ½ tsp baking powder
- 03 ¼ tsp baking soda
- 04 ¼ tsp salt
- 05 1 cup unsalted butter, softened
- 06 1 ¼ cups granulated sugar
- 07 3 large eggs, room temperature
- 08 Zest of 2 lemons
- 09 ¼ cup fresh lemon juice
- 10 ½ cup buttermilk
- 11 1 tsp vanilla extract
- 12 1 cup fresh blueberries
Lemon Glaze (optional)
- 01 1 cup powdered sugar
- 02 2‑3 tbsp fresh lemon juice
- 03 1 tsp lemon zest
Instructions
Preheat the oven to 350°F (175°C). Line a 9×13‑inch sheet pan with parchment paper; this helps the cake release easily.
In a bowl, whisk together flour, baking powder, baking soda, and salt; set aside.
Cream butter and sugar until pale and fluffy, about 3‑4 minutes. Add eggs one at a time, mixing well after each.
Stir in lemon zest, lemon juice, and vanilla. Gently fold in the dry ingredients alternating with buttermilk, beginning and ending with the flour mixture.
Toss blueberries with a tablespoon of flour, then fold them into the batter, being careful not to crush them.
Spread batter evenly in the prepared pan. Sprinkle a few extra blueberries on top for visual appeal.
Bake for 30‑35 minutes, or until a toothpick inserted in the center comes out clean and the top is golden.
Allow the cake to cool in the pan for 10 minutes, then remove onto a wire rack. If using glaze, drizzle it over the warm cake now.

- 1 If the batter looks too thick, add a tablespoon more buttermilk; it should be pourable.
